Kareem Abdul-Jabbar aired his concerns and fears after Donald Trump became the president-elect early Wednesday morning.

In a piece for the Washington Post, Abdul-Jabbar spoke of his "rage of betrayal," saying the country opted for the leadership of a racist.

"Let the other groups denigrated and threatened by Trump speak for themselves," Abdul-Jabbar wrote. "The women, immigrants, Muslims, Jews, the LGBT community and others who now must walk through the streets of their country for the next four years in shame and fear, knowing that their value as human beings has been diminished by their neighbors. I only speak for myself as an African American and I speak with the rage of betrayal."

Abdul-Jabbar went on to list inequalities African Americans face in today's world, including lower pay and higher job discrimination, less educational opportunity and greater health problems.

According to the former NBA star, the majority of white voters who chose Trump are afraid of "the changing shade of skin color of America."

"As the Latino, Asian and black population rises, the white majority will soon disappear," Abdul-Jabbar wrote. "Between 2000 and 2010, whites dropped from 75.1 percent of the population to 63.7 percent. By 2050, whites will be in the minority at 47 percent. Trump represents the last wisp of the rich white plantation owner holding on to the glories of the past."

Abdul-Jabbar's solution is for African Americans to band together with other minorities to work hard to preserve America's ideals that those minorities hold dear and to take action now.
